IMPROVEMENT IN GAR-TRUCKS.

Specification forming part of Letters Patent No. 50,594, dated October 24. 1865.

.To all whom it may concern:

. Be it knownl that I, CHARLES F. J nearer,-

of Aurora, Kane county, State of Illinois, have invented a new and Improved Swing-Beam Truck; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making'a part of this specification, in whic Figure 1 is a sectional plan view of the improvedtruck. Fig. 2 is a sectional end view of the same. Fig. 3 is aside elevation of the truck.

Similar letters of reference indicate corresponding parts in the three figures.

This invention relates particularly to the trucks of locomotives and tenders, and is in- 'tended'for preventingcoircusstons;and conse: qnently injury to the engine and rails.

The nature of my inventionconsists in: mounting the engineer tender upon a trans versebeam'or equalizer, which is suspended, by Ineansof stirrups beneath springs that have bearings directly over and upon the journal-. boxes of the axles,'in such manner that the em.

tire weight of the engine or tender, as the case may be, shall be supported upon said journal boxes, and the engine allowed freedom .to oscillate in a lateral direction with respect to the track, according to the impetus whichit may receive, as will be hereinafter described.

To enable others skilled intheart to unde'rstand my invention, I will describe its con struction and operation.

In the accompanying drawings'I have represented an engine-truck having outside bearings; but I contemplate applyin'g'the invention which I am aboutto describe to any kind .of truck, and to employ either outside or inside bearings without changing the principle of the invention. a

A represents the vertical center pivot of the truck, thelower end of which passes .freely through a rocking block,B, and also through the horizontal transverse equalizing-beam E, as shown in the half-sectional view, Fig. 2. The hole through the beam E for receiving the center pivot, A, is made slightly flaring, for the purpose of allowingthe block B audits center pivot a slight rocking movemen t upon the semispherical bearing-block G.

The beam E is arranged. at an intermediate point between the axles of the wheels, and it is suspended from semi-elliptic springs F F by means of pivoted hangers HH, the upper ends of which are pivoted to ears which are formed on hands Gr G,:that are shrunk upon the springs FF, as shown in Figs. 1 and 2, v

The extremities of the springs F F are held in place and guided by means of the pockets K K, which are securelybolted over the journal-boxesJ, so that all the weight which comes upon the beam E will be transferred uniformly upon said boxes J through themedium of the springs F F, and consequently will be supported by the axles of the truck-wheels.

' Directly beneath the hands G Gof thesprin gs F F, and supported upon the upper tierodsof the truck i'rame; are "guides for keeping the springs from receiving any undue lateral strain. These guides I I receive the springs F F, and and also the spring-ba'ndsG Gr, between their projecting arms, so as not only to prevent lateral play of the springs, but also to check any longitudinal movements of these springs which would have a tendencyto displace them.

.-It will beseenfrom the drawings that Ie n' ploy two pair of hangers at each endof the sw'ingrbeam E, arranged on both sides of the jspringsF'F, so that I not only obtain great strength thereby, butI perfectly balance the "beam on the springs by causing the strain to fall uniformly upon eachside thereof. Having thus described my invention, what I claim 'as new, and desire to secure by Letters Patent, is- T 1. suspending theswi'ng-beam E from springs F F .bymeans of hangersHH, in combination with the straps'G G and spring-guides If, all operating substantially as described, for the purpose of admitting lateral movement and transferring the weight upon the swing-beam to the axles, as set forth.

2.- Sustaining-the swing-beam E by means of a'pair of suspenders, H, on each side ofeach.

spring, substantially as described.
